This arm which is designated at 24 is rounded ofi on its outer surface 25 to form a continuation of the contour of the endpiece supporting member.

The opposite arm of the T-shaped member is bifurcated to form a pair of opposed hinge ears 26 and 2'? having an opening 28 therebetween for receiving the forward end 11 of the temple 13. These ears are substantially circular in contour and are formed with registering openings 29 for the purpose of receiving the pivot 30 which hingedly connects the temples to the endpiece. There is also formed between the ears 26 and 27 an abutment 31 adapted to receive the small projection 12 on the temples and thereby limit the outward movement of the temple aboutthe pivot 30.

When the endpieces are positioned above the normal field of useful'side vision as shown in Figures 1 to 4 inclusive, it is necessary that the axis of the temple hinge joint be inclined with respect to the plane of the lenses in order to properly position the spectacles on the face. The leg 15 of the endpiece is therefore made wedgeshaped or wider adjacent the top than adjacent the bottom. Then when the leg 15 is placed with its front'face flat against the rear face of the lug 9 as illustrated in Figure 5, the hinge joint will be inclined. By properly forming the angle between the front and rear faces of the leg 15, any desired angle of the temple may be obtained.

It will be appreciated from the above that an endpiece construction has been provided which may be firmly and quickly anchored to the nonmetallic lugs provided for the purpose on the spectacle front, such'endpiece is extremely simple both in its construction and in the process of manufacture, and that it is a very strong and durable construction not likely to become easily damaged or rendered inoperative.

It is particularly pointed out that by virtue of the strong abutment piece formed by the arm 24 of the T-shaped member there is provided a construction which will enable the endpiece to be positively and accurately positioned with respect to the rest of the frame by simply moving this abutment until it abuts against the end of the endpiece supporting lugs, and after the endpiece has been anchored in place by means of the rivets21 and 22, this arm 24 serves the purpose of taking up the force exerted tending to bend the endpiece when the temple is opened. It is pointed out in this connection that when the temple is swung to its open position, the part 12 on the temple will bear against the abutment 31 on the endpiece, and were it not for the abutment between the arm 24 and the ends of the endpiece supporting lugs, this force might easily bend or break the hinge member from the relatively thin flat leg 15. Such action however is positively prevented by virtue of the arm just mentioned which is of sufficiently heavy con- T the barrel orhinge arm consisting of the ears 33 and 34, are positioned with their axis inclined to the leg 31, instead of making one edge of the leg 31 thicker than the other to incline the hinge.

The form shown in Figure 7 is the same as shown in Figures 1 to 5 with the exception that the rivets 35 on the leg 36 are formed integral therewith. It is also noted that the rivets 32 in Figure 6 and the rivets 35 in Figure 7 are squared instead of rounded in Figures 3 and 5.

Figures 8 and 9 illustrate slightly different forms of construction in which the leg of the T-shaped member and the rivets previously described have been replaced by the prongs 37 and 38 in Figure 8 and 41- and 42 in Figure 9. In Figure 8 these prongs 3'7 and 38 are arranged on substantially the same level, one behind the other and are provided with barbed points 39 and 40. Prongs 37 and 38 project from the abutment surface 23 substantially at right angles thereto, and are adapted to be forced into the end of the endpiece supporting lug to secure the endpiece thereto. The form shown in Figure 9 is substantially the same as that shown in Figure 8 with the exception that the prongs 41 and 42 are positioned one above the other. These prongs are likewise provided with barbed points 43 and 44 adapted to be forced into the endpiece supporting lug. In any of the various forms the outer surface of the part 24 may be provided with suitable engraving as shown in Figure 9.

Attention is directed to the fact that the above described metallic endpieces are of such form that any one form may be made by rolling out a long strip or wire of the proper cross section and cutting off successive short portions of a thickness to form an endpiece. The hinge barrel may then be bifurcated, and with a relatively slight amount of finishing, the complete endpiece maybe formed. In the case of the form shown in Figure 6 it will be necessary to mill out between the rivets and in Figure 7 on the opposite sides of the rivets. Likewise, in Figure 8 it will be necessary to mill out on opposite sides of the prongs and in Figure 9, between the prongs, because in either case the rolling would leave a continuous tongue or tongues instead of the individual rivets or prongs. In any case, however, the process, of manufacture is relatively simple and inexpensive, and may be carried out very rapidly and accurately.

It is to be clearly understood that the foregoing is by way of illustration only and that the spirit and scope of this invention is not to be limited thereby, but is to be limited only by the prior art and by the terms of the appended claims.
